Hey! Not only am I a huge fan of your products, but I am also the founder of a technology that I think you would really like for contests just like this. We built a system that automates and tracks social sharing for contests so you can know automatically if someone shared posts of your choosing to promote campaigns like this. I'd love to chat with you about it. You can find us at perksocial.com, or reply to me and I'll tell you more.
Thanks for making incredible products and prices that just make it impossible not to buy!
